We're dividing 33488390 by 609 
The aim is to understand the frequency of 609 in 33488390.

On to step 1:
The number 609 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 609

Let's proceed to step 2:
When dividing 33 by 609, we get 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 609

Step 3:
If we divide 334 by 609, we get 0 and a remainder of 334.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 334, we end up with 334.
Append the next digit (8) from the dividend to 334 and continue with: 3348 / 609

Let's proceed to step 4:
3348 divided by 609 is 5 with a remainder of 303.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 3045 from 3348 to get 303.
Bring next digit (8) of the dividend behind the 303 and repeat the process: 3038 / 609

Advancing to step 5:
The number 609 fits into 3038 4 times, leaving a remainder of 602.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
Subtracting 2436 from 3038 leaves us with 602.
Take the next digit (3) from the dividend and append it to 602, then repeat: 6023 / 609

Step 6:
When dividing 6023 by 609, we get 9 with a remainder of 542.
Use 9 as the next digit of our solution. 
Result so far: 549.0
Subtracting 5481 from 6023 leaves us with 542.
Bring next digit (9) of the dividend behind the 542 and repeat the process: 5429 / 609

On to step 7:
5429 divided by 609 is 8 with a remainder of 557.
Put 8 as the next digit of the answer. 
Result so far: 5498.0
The remainder is 557 after subtracting 4872 from 5429.
Bring next digit (0) of the dividend behind the 557 and repeat the process: 5570 / 609

Going ahead to step 8:
5570 divided by 609 is 9 with a remainder of 89.
Put 9 as the next digit of the answer. 
Result so far: 54989.0
Subtracting 5481 from 5570 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 9:
890 divided by 609 is 1 with a remainder of 281.
Put 1 as the next digit of the answer. 
Result so far: 54989.1
If we take 609 away from 890, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 10:
609 goes into 2810 4 times with a remainder of 374.
The next digit of our result is 4. 
Result so far: 54989.14
Subtract 2436 from 2810 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 11:
609 goes into 3740 6 times with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 54989.146
Subtract 3654 from 3740 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 12:
609 goes into 860 1 times with a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 54989.1461
Subtracting 609 from 860 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 13:
The number 609 fits into 2510 4 times, leaving a remainder of 74.
The next digit of our result is 4. 
Result so far: 54989.14614
The remainder is 74 after subtracting 2436 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 14:
609 goes into 740 1 times with a remainder of 131.
The next digit of our result is 1. 
Result so far: 54989.146141
The remainder is 131 after subtracting 609 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 15:
609 goes into 1310 2 times with a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 54989.1461412
Subtracting 1218 from 1310 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 16:
The number 609 fits into 920 1 times, leaving a remainder of 311.
Use 1 as the next digit of our solution. 
Result so far: 54989.14614121
Subtract 609 from 920 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

The final result is 54989.14614121 with a remainder of 3.11e-07.
